Changeset [810ab1e1324e] by hsoft

Improved selection handling during ref-swapping under dupes-only mode.

Previously, our selection would simply be lost (because the dupes that were
just swapped wouldn't be present in the table). Now, instead of trying to
preserve our dupe-selection, we preserve our index-selection when in dupes-only
mode. [#222]
